Is there a place for medical treatment in children with gallstones?
BACKGROUND: Medical treatment of gallstones with ursodeoxycholic acid (UDCA) or chenodeoxycholic acid (CDCA) has not been evaluated in children.
AIM: The purpose of this study was to assess the effectiveness of UDCA in the treatment of gallstones in children.
METHODS: UDCA was used to treat 15 patients, (7 boys and 8 girls; mean age, 7.8 years; range, 3 months to 15 years) for 1 year. All had radiolucent stones with a maximum diameter of 10 mm and a normally contractile gallbladder.
RESULTS: The stones disappeared completely in two children but returned later. All symptomatic patients became symptom free.
CONCLUSION: UDCA is ineffective in the treatment of gallstones in children except in terms of relieving symptoms while on treatment

Questa lettura non deve interessare solo gli allievi, ma anche e soprattutto il corpo docente, che deve sviluppare la sua preparazione attraverso un costante aggiornamento culturale e deve riuscire ad instaurare un rapporto tale con l'allievo da fargli apprezzare e capire il valore e l'importanza dell'architettura, che non può essere confinata in un angolo ammuffito dei nostri interessi primari, ma deve contribuire a migliorare il nostro sistema di vita
Nutrition and physical activity in the prevention and treatment of sarcopenia: systematic review
This systematic review summarizes the effect of combined exercise and nutrition intervention on muscle mass and muscle function. A total of 37 RCTs were identified. Results indicate that physical exercise has a positive impact on muscle mass and muscle function in subjects aged 65 years and older. However, any interactive effect of dietary supplementation appears to be limited. Introduction: In 2013, Denison et al. conducted a systematic review including 17 randomized controlled trials (RCTs) to explore the effect of combined exercise and nutrition intervention to improve muscle mass, muscle strength, or physical performance in older people. They concluded that further studies were needed to provide evidence upon which public health and clinical recommendations could be based. The purpose of the present work was to update the prior systematic review and include studies published up to October 2015. Methods: Using the electronic databases MEDLINE and EMBASE, we identified RCTs which assessed the combined effect of exercise training and nutritional supplementation on muscle strength, muscle mass, or physicalperformance in subjects aged 60 years and over. Study selection and data extraction were performed by two independent reviewers. Results: The search strategy identified 21 additional RCTs giving a total of 37 RCTs. Studies were heterogeneous in terms of protocols for physical exercise and dietary supplementation (proteins, essential amino acids, creatine, β-hydroxy-β-methylbuthyrate, vitamin D, multi-nutrients, or other). In 79% of the studies (27/34 RCTs), muscle mass increased with exercise but an additional effect of nutrition was only found in 8 RCTs (23.5%). Muscle strength increased in 82.8% of the studies (29/35 RCTs) following exercise intervention, and dietary supplementation showed additional benefits in only a small number of studies (8/35 RCTS, 22.8%). Finally, the majority of studies showed an increase of physical performance following exercise intervention (26/28 RCTs, 92.8%) but interaction with nutrition supplementation was only found in 14.3% of these studies (4/28 RCTs). Conclusion: Physical exercise has a positive impact on muscle mass and muscle function in healthy subjects aged 60 years and older. The biggest effect of exercise intervention, of any type, has been seen on physical performance (gait speed, chair rising test, balance, SPPB test, etc.). We observed huge variations in regard to the dietary supplementation protocols. Based on the included studies, mainly performed on well-nourished subjects, the interactive effect of dietary supplementation on muscle function appears limited
